Product overview
Description
The L99UDL01 is a multiple half-bridge IC with 6 integrated outputs that are PWM configurable and current regulated and up to two externally configured half bridges for higher current nodes. The level of diagnostics includes open load, short to battery, short to ground, and load integrity via 10 bit current feedback.
The L99UDL01 is commanded entirely by SPI using duration and current level commands.
